In some embodiments, the invention relates to the method of making the above glove.

The present invention may be understood more readily by reference to the following detailed description of illustrative and preferred embodiments that form a part of this disclosure. It is to be understood that the scope of the claims is not limited to the specific devices, methods, conditions or parameters described and/or shown herein, and that the terminology used herein is for the purpose of describing particular embodiments by way of example only and is not intended to be limiting of the claimed invention. Also, as used in the specification including the appended claims, the singular forms “a,” “an,” and “the” include the plural, and reference to a particular numerical value includes at least that particular value, unless the context clearly dictates otherwise. When a range of values is expressed, another embodiment includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent “about,” it will be understood that the particular value forms another embodiment. All ranges are inclusive and combinable.

Examples of suitable fibers for use in the layers include polyaramids, such as poly(paraphenylene terephthalamide) sold by E. I. du Pont de Nemours and Company (DuPont), Wilmington, Del. under the trade name KEVLAR®.

When the polymer is a polyamide, aramid is preferred. By “aramid” is meant a polyamide wherein at least 85% of the amide (—CO—NH—) linkages are attached directly to two aromatic rings. Aramid fibers are disclosed in U.S. Pat. Nos. 4,172,938; 3,869,429; 3,819,587; 3,673,143; 3,354,127, and 3,094,511. Additives can be used with the aramid, and it has been found that up to as much as 10 percent, by weight, of other polymeric material can be blended with the aramid. Also, copolymers can be used having as much as 10 percent of other diamine substituted for the diamine of the aramid or as much as 10 percent of other diacid chloride substituted for the diacid chloride or the aramid.

Two common types of aramid fibers include (1) meta-aramid fibers, one of which is composed of poly(metaphenylene isophthalamide), which is also referred to as MPD-I, and (2) para-aramid fibers, one of which is composed of poly(paraphenylene terephthalamide), also referred to as PPD-T. Meta-aramid fibers are currently available from DuPont in several forms under the trademark Nomex®. Commercially available Nomex® T-450 is 100% meta-aramid fiber; Nomex® T455 is a staple blend of 95% Nomex® meta-aramid fiber and 5% Kevlar® para-aramid fiber; and Nomex® T462 is a staple blend of 93% Nomex® meta-aramid fiber, 5% Kevlar® para-aramid fiber, and 2% carbon core nylon fiber. Nomex® N302 is a staple blend of 93% producer-colored Nomex® meta-aramid fiber, 5% producer-colored Kevlar® para-aramid fiber, and 2% carbon core nylon fiber. In addition, meta-aramid fibers are available in various styles under the trademarks Conex® and Apyeil® which are produced by Teijin, Ltd. of Tokyo, Japan and Unitika, Ltd. of Osaka, Japan, respectively.

The preferred aramid is a para-aramid and poly(p-phenylene terephthalamide)(PPD-T) is the preferred para-aramid. By PPD-T is meant the homopolymer resulting from approximately mole-for-mole polymerization of p-phenylene diamine and terephthaloyl chloride and, also, copolymers resulting from incorporation of small amounts of other diamines with the p-phenylene diamine and of small amounts of other diacid chlorides with the terephthaloyl chloride. As a general rule, other diamines and other diacid chlorides can be used in amounts up to as much as about 10 mole percent of the p-phenylene diamine or the terephthaloyl chloride, or slightly higher, provided only that the other diamines and diacid chlorides have no reactive groups which interfere with the polymerization reaction. PPD-T, also, means copolymers resulting from incorporation of other aromatic diamines and other aromatic diacid chlorides such as, for example, 2,6-naphthaloyl chloride or chloro- or dichloroterephthaloyl chloride or 3,4′-diaminodiphenylether.

By “animal fibers” is meant textile fibers of animal origin including, but not limited to, wool, cashmere, alpaca, camel hair, and silk.

By “plant fibers” is meant textile fibers of plant origin including, but not limited to, cofton, kapok, jute, ramie, flax, and blends or mixtures thereof.

For purposes herein, the term “fiber” is defined as a relatively flexible, macroscopically homogeneous body having a high ratio of length to width across its cross-sectional area perpendicular to its length. The fiber cross-section can be any shape, but is typically round. Herein, the term “filament” or “continuous filament” is used interchangeably with the term “fiber.”

As used herein, the term “staple fibers” refers to fibers that are cut to a desired length or fibers that occur naturally with or naturally have a low ratio of length to width across its cross-sectional area perpendicular to its length when compared with filaments. Length can vary from about 0.1 inch to several feet. In some embodiments, the length is from 0.1 inch to about 8 inches. Man-made staple fibers are cut to a length suitable for processing on cotton, woolen, or worsted yarn spinning equipment.

The staple fibers can have (a) substantially uniform length, (b) variable or random length, or (c) subsets of the staple fibers have substantially uniform length and the staple fibers in the other subsets have different lengths, with the staple fibers in the subsets mixed together forming a substantially uniform distribution.

In some embodiments, suitable staple fibers have a length of 1 to 30 centimeters. Staple fibers made by short staple processes result in a fiber length of 1 to 6 centimeters.

The staple fibers can be made by any process. The staple fibers can be formed by stretch-breaking continuous fibers resulting in staple fibers with deformed sections that act as crimps. The staple fibers can be cut from continuous straight fibers using a rotary cutter or a guillotine cutter resulting in straight (i.e., non crimped) staple fiber, or additionally cut from crimped continuous fibers having a saw tooth-shaped crimp along the length of the staple fiber, with a crimp (or repeating bend) frequency of no more than 8 crimps per centimeter.

Stretch-broken staple fibers can be made by breaking a tow or a bundle of continuous filaments during a stretch-break operation having one or more break zones that are at a prescribed distance creating a random variable mass of fibers having an average cut length controlled by break-zone adjustment.

Staple fibers of this invention can be converted into yarns using traditional long and short staple ring spinning processes that are well known in the art. For short staple, cotton system spinning fiber lengths from ¾inch to 2 ¼inch (1.9 to 5.7 cm.) are typically used. For long staple, worsted, or woolen system spinning, fibers up to 6 ½inches (16.5 cm.) are typically used. However, this is not intended to be limiting to ring spinning because the yarns may also be spun using air jet spinning, open end spinning and many other types of spinning that converts staple fiber into useable yarns.

The stretch-broken staple fibers typically have length of up to 7 inches (17.8 cm.) long and can be made using traditional stretch-broken tow processes. Staple fibers having maximum lengths of up to around 20 inches (51 cm) are possible through processes as described, for example in PCT Patent Application No. WO 0077283. Yarns are so made by consolidated fibers into spun yarn using filament entanglement with air jets having a tenacity in the range of 3 to 7 grams per decitex. These yarns may have secondary twist, that is, they may be twisted after formation to impart more tenacity to the yarn, in which case the tenacity can be in the 10 to 18 grams per denier (9 to 17 grams per dtex) range. Stretch-broken staple fibers normally do not require crimp because the process imparts a degree of crimp into the fiber.

The term continuous filament refers to a flexible fiber having relatively small-diameter and whose length is longer than those indicated for staple fibers. Continuous filament fibers can be converted to multifilament yarns by processes well known to those skilled in the art.

Fabrics of this invention can take on numerous configurations, including, but not limited to, knitted or woven fabrics or non-woven structures. Such fabric configurations are well known to those skilled in the art.

By “non-woven” fabric is meant a network of fibers typically in a random orientation but can be unidirectional (if contained within a matrix resin), felt, fiber batts, and the like.

By “woven” fabric is meant a fabric woven using any fabric weave, such as plain weave, crowfoot weave, basket weave, satin weave, twill weave, and the like. Plain and twill weaves are believed to be the most common weaves used in the trade.

The invention is exemplified by the following examples, which are not intended to limit the scope of the invention.

Examples Comparative Example A

In Comparative Example A, the oven gloves, available from JE Enterprises under the trademark “OveGlove”®, had an outer layer of Kevlar® 29, Nomex® 450, 1.7 dtex denier spun yarn with a linear density of 1.7 dtex denier, and a hand contact layer of polyester and cotton. These gloves were conditioned by total immersion in water at room temperature for 2 minutes. However, the immersion in water was done in a manner that prevented water from entering the interior of the glove through the wrist or arm opening. Gloves were then removed from the water and hung in a vertical position for 5 minutes. The gloves were tested as below within 5 minutes of completion of the conditioning.

Conditioned gloves were placed on a hotplate surface at temperature of 280 C.±5 C., (536 F.+18 F.). Recording of temperatures inside the glove was begun as soon as the gloves were in place on the hotplate. Temperatures inside the glove were measured by taping three Omega K-type thermocouples to the palm area.

The individual temperature from each thermocouple (TC 1-TC3) and their average as a function of time are presented in Table 1. The average temperature reaches 84.1 C. (183.4 F.) in 12 seconds (s). A typical task time for a person to remove an article at an elevated temperature from an oven or other heat source is about 15 seconds and the temperature at which one would experience discomfort is about 49 C.-55 C. (120 -131 F.). Of course, the level of discomfort and the temperatures will vary from person to person.
